JEDEC Information
JEDEC is used to determine what classification level should be used for initial
reliability qualification. Once identified, the LEDs can be properly packaged, stored
and handled to avoid subsequent thermal and mechanical damage during the
assembly solder attachment and/or repair operation. The present moisture sensitivity
standard contains six levels, the lower the level ,the longer the devices floor life. PLCC
3528 series are certified at level 2a. This means PLCC 3528 series have a floor life of
4 weeks before PLCC 3528 series need to re-baked.

Precaution for Use
Storage
1.1 Before opening the package
The LEDs should be kept at <40℃ & <90%RH. The LEDs should be used within a
year. When storing the LEDs, moisture proof package with absorbent material
(silica gel) is recommended.
1.2 After opening the package
The LEDs should be kept at ≦30℃ & ≦60%RH. The LEDs should be soldered within
168 hours (7days) after opening the moisture proof package.
If unused LEDs remain, they should be stored in moisture proof packages, such as
sealed containers with moisture proof package within absorbent material (silica
gel).It is also recommended to return the unused LEDs to the original moisture
proof package and to seal the moisture proof package again.
If the moisture absorbent material (silica gel) vapors or expires the expiration date,
baking treatment should be performed by using the following conditions : 60℃ for
20 hours.
The LEDs electrode and leadframe comprise a silver plated copper alloy. The silver
surface may be affected by environments. Please avoid conditions which may
cause the LEDs being corroded or discolored. The corrosion or discoloration might
lower solderability or affect optical characteristics.
Please avoid rapid transition in ambient temperature, especially in high humidity
environments where condensation can occur.
Static electricity
The products are sensitive to static electricity and highly taken care when handling
them.
Static electricity or surge voltage will damage the LEDs. It is recommended to wear an
anti-electrostatic wristband or an anti-electrostatic glove when handling the LEDs.
All devices, equipments and machinery must be properly grounded. It is
recommended that measures be taken against surge voltage to the equipment that
mounts the LEDs.
